If I could score a copy of 1st edition space marine for a non-"MIB OOP ANTIQUE MUCHO $$$" type price, would it be worth it, as someone who has no real pressing intention of playing it?
I might just get it for the included miniatures, but would you say there was any cool factor in owning a copy regardless? I own a copy of 2nd edition space marine, is 1st edition different enough to purchase (fluffwise/ruleswise/etc), in your estimation?
-Periodic, knowing this is might be a moot question for some of you with your gazillion point armies and stacks of unused plastic sprues
?Orks and Eldar were not included, they were sold in separate boxed sets. The buildings are great and you do get a lot of counters, burst templates, etc., many are still useable in SM2, E40K & E-A. ?And to play a 2000-3000 point game: 4-6 hours. Again, I started with SM1/AT1 and we still use some of the rules in our "Hybrid" system. ?I used to play solitaire SM1 skirmishes with 1000-2000 point games, it was a lot of fun and I always won ! 
Between SM1, SM2, Titan Legions, and Epic40k I'll have enough buildings to do full-scale urban combat.
